Cleveland C01453 1/8 Inch Hss Left Hand Jobber Drill Bit

Product Description

The CLEVELAND C01453 is a jobber-length twist drill bit designed for left-hand cutting in general-purpose drilling applications. Manufactured from high-speed steel with a bright, uncoated finish, this bit features a 118-degree standard point angle and a regular spiral flute configuration with web thinning for improved chip clearance and reduced thrust at entry. The straight-cylindrical shank measures 1/8 inch in diameter, making it compatible with standard drill chucks. At 2.75 inches overall length with a 1.625-inch flute length, the C01453 conforms to ASME B94.11M standards and carries an ANSI specification designation. Licensed machinists, pipefitters, and metal fabricators reach for this bit when left-hand extraction or reverse-rotation drilling is required.

The C01453 is sized at 0.1250 inch (1/8 inch) diameter and is recommended for use in aluminum and similarly machinable materials. Left-hand cut bits are commonly used in screw extraction setups, where the reverse rotation of the drill can back out a fastener while the hole is being drilled, eliminating the need for a separate extraction step. This bit is suited to benchtop drill presses, hand drills, and reversible power tools in both shop and field environments.

Key Features

• Left-hand cutting direction for reverse-rotation drilling and screw extraction workflows
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• High-speed steel construction provides durability across general-purpose metal drilling
• Bright, uncoated finish — suitable for use with cutting fluid where needed
• 2-flute regular spiral design promotes efficient chip evacuation
• Conforms to ASME B94.11M and ANSI specification standards

Compatibility

Designed as an OEM-style general-purpose jobber-length drill bit in the Cleveland Series 2006 line, suitable for use in standard 1/8-inch straight-shank drill chucks across benchtop and handheld drilling equipment.

Installation Notes

Left-hand drill bits require a reversible drill or drill press set to counterclockwise rotation. Secure the workpiece firmly before drilling to prevent movement under reverse torque. Use appropriate cutting fluid when drilling non-ferrous metals to extend bit life and improve hole quality. Inspect the bit for chipping or edge wear before each use, and replace if the cutting edge is compromised.
